💼 Career

Knowing how to use Bootstrap classes for tables is a valuable skill for front-end developers and web designers working on professional websites and applications.

1

Create the basic HTML structure with Bootstrap CSS

Write the basic HTML5 skeleton with lang="en", charset="UTF-8", and a viewport meta tag. Include the Bootstrap 5 CSS CDN link inside the <head>. Inside the <body>, add a <main> element with a <table> element having the class table. The table should have a header row with two columns: Fruit and Color. Do not add any table rows yet.

Add table rows with fruit names and colors

Inside the <tbody>, add exactly five <tr> rows. Each row should have two <td> cells: the first with the fruit name and the second with its color. Use these exact pairs in order: Apple - Red, Banana - Yellow, Grapes - Purple, Orange - Orange, Kiwi - Green.

Practice

1. What does the table-striped class do in a Bootstrap table?

easy

A. Adds alternating background colors to table rows for easier reading.

B. Highlights the row when you hover the mouse over it.

C. Makes the table borders thicker.

D. Changes the font style of the table text.

Solution

1. Step 1: Understand the purpose of table-striped

   The table-striped class adds alternating background colors to rows, making it easier to read data across the table.

2. Step 2: Differentiate from other classes

   The table-hover class highlights rows on mouse hover, which is different from table-striped.

3. Final Answer:

   Adds alternating background colors to table rows for easier reading. -> Option A

4. Quick Check:

   Striped = alternating row colors [OK]

Hint: Striped means alternating colors on rows [OK]

Common Mistakes:

• Confusing striped with hover effect
• Thinking it changes font or borders
• Assuming it highlights on mouse hover

2. Which is the correct way to add both striped and hover effects to a Bootstrap table?

easy

A. <table class='table-striped-hover'>

B. <table class='table-hover table-striped'>

C. <table class='striped hover'>

D. <table class='table table-striped table-hover'>

Solution

1. Step 1: Check Bootstrap class syntax

   Bootstrap requires the base table class plus additional classes separated by spaces, like table-striped and table-hover.

2. Step 2: Validate correct class order and spelling

   <table class='table table-striped table-hover'> correctly uses class='table table-striped table-hover'. Order doesn't matter but all classes must be present and spelled correctly.

3. Final Answer:

   <table class='table table-striped table-hover'> -> Option D

4. Quick Check:

   Use base table plus both classes [OK]

Hint: Always include base 'table' class with modifiers [OK]

Common Mistakes:

• Omitting the base 'table' class
• Combining classes without spaces
• Using incorrect class names

3. Given this HTML snippet, what visual effect will the table have?

<table class='table table-striped table-hover'>
  <tr><td>Row 1</td></tr>
  <tr><td>Row 2</td></tr>
  <tr><td>Row 3</td></tr>
</table>

medium

A. Rows alternate background colors and highlight on mouse hover.

B. Rows have no background color but highlight on mouse hover.

C. Rows alternate background colors but do not highlight on hover.

D. Table has no special background or hover effects.

Solution

1. Step 1: Identify classes used

   The table uses table-striped and table-hover classes together.

2. Step 2: Understand combined effects

   table-striped adds alternating row colors, and table-hover highlights the row under the mouse pointer.

3. Final Answer:

   Rows alternate background colors and highlight on mouse hover. -> Option A

4. Quick Check:

   Striped + Hover = alternating colors + highlight [OK]

Hint: Both classes combine their effects visually [OK]

Common Mistakes:

• Thinking only one effect applies
• Ignoring hover effect
• Confusing hover with striped effect

4. What is wrong with this table code if the hover effect does not work?

<table class='table table-striped hover'>
  <tr><td>Data</td></tr>
</table>

medium

A. The table-striped class disables hover effect.

B. The table class is missing.

C. The class should be table-hover, not just hover.

D. Hover effect requires JavaScript to work.

Solution

1. Step 1: Check class names

   The class hover alone is not a valid Bootstrap class for hover effect.

2. Step 2: Correct class for hover effect

   The correct class is table-hover, which must be used with the base table class.

3. Final Answer:

   The class should be table-hover, not just hover. -> Option C

4. Quick Check:

   Hover effect needs table-hover class [OK]

Hint: Hover class must be 'table-hover' exactly [OK]

Common Mistakes:

• Using 'hover' instead of 'table-hover'
• Omitting 'table' base class
• Assuming hover needs JavaScript

5. You want a table that has striped rows, highlights on hover, and also makes the header row stand out with a dark background. Which is the best way to achieve this using Bootstrap classes?

hard

A. <table class='table table-striped table-hover'> <thead class='table-header-dark'> ... </thead> </table>

B. <table class='table table-striped table-hover'> <thead class='table-dark'> ... </thead> </table>

C. <table class='table table-striped table-hover'> <thead class='thead-dark'> ... </thead> </table>

D. <table class='table table-striped table-hover table-dark'> ... </table>

Solution

1. Step 1: Combine striped and hover classes on table

   Use table-striped and table-hover with the base table class for row effects.

2. Step 2: Use correct class for dark header

   Bootstrap uses table-dark on the <thead> element to style the header with a dark background.

3. Step 3: Verify other options

   table-dark on the whole table changes entire table style, not just header. thead-dark is deprecated in Bootstrap 5+. table-header-dark is not a valid class.

4. Final Answer:

   <table class='table table-striped table-hover'> <thead class='table-dark'> ... </thead> </table> -> Option B

5. Quick Check:

   Use table-dark on thead for dark header [OK]

Hint: Dark header uses 'table-dark' on thead element [OK]

Common Mistakes:

• Applying 'table-dark' to whole table instead of header
• Using deprecated 'thead-dark' class
• Inventing non-existent classes like 'table-header-dark'
